2 Where C is the speed of light, m / s; VF is the speed factor (the ratio of the speed of propagation of an
electromagnetic wave in a cable to the speed of propagation of an electromagnetic wave in a vacuum), takes on a
value depending on the cable from 0.1 to 1; S - scanning frequency range (Hz).
3 It depends on the amount of attenuation in the cable and is the limit of the indication.
